You can't have a single compound which randomly gives out different emission lines when in a flame. What you have found with different elements giving out different colors when in a flame are basically emission lines of those atoms: the flame excites certain electronic transition in those atoms, resulting in light being emitted. Now, those transitions are so ...

Cyanide world. Your other question Appearance of an Ammonia World's Atmosphere got me thinking more about this. Here is my new idea for the cycle. Photosynthesis: energy + N2 + CH4 -> HCN + NH3. Energy is stored in the CN triple bond. Heterotrophs: NH3 + CN -> CH4 + N2 I admit I am struggling mightily with the enthalpy of the heterotroph part....

Same effect. https://www.pca.state.mn.us/air/chlorofluorocarbons-cfcs-and-hydrofluorocarbons-hfcs Halon is specifically listed as harmful to the ozone layer. Bromine does the same evil that Chlorine does. As for the question itself, from the source HFCs, CFCs and HFCs contribute an estimated 11.5% to present-day effect of GHGs on climate and climate change....

(Warning: TvTropes links abound.) Frame challenge: You basically want a brown note. This is a sufficiently common trope that it may be better to not explain it, because trying too hard risks either losing your audience with an implausible (or disturbing or distasteful) explanation, or being worse than what your audience comes up with on their one (note). ...

The movie shows clear logical every-day steps that allows a person to create a doomsday device So imagine a 45 minute movie that gives any person, no matter ability skill or how 'sound of mind', simple instructions to create an all-powerful device that will certainly cause the death of everyone. For instance, by knowing somehow a system of quantum mechanics ...

Propaganda This is arguably already happening in the world. Your hypothetical alien creates a film arguing that COVID originated from a Chinese lab as a weapon of war, that the virus was actually released by the Chinese government to damage all other economies, etc. Some people will be ready to believe this kind of theory, and once they watch the film, they'...

This isn't quite what you're looking for, but if you're happy to settle for 'causes mass instability and drives many people insane', consider revealing some terrible truth about the world. The example that came to mind was an event in Scott Alexander's Unsong, where the Devil releases a video tape which he forced a deceased National Geographic presenter to ...

An Actual Scientific Answer: Use Shepard Tones Shepard tones are a certain pattern of sounds that trick the ear into believing that the pitch or rhythm is infinitely increasing or decreasing. Extended exposure is known to cause panic and anxiety attacks in people. SOURCE: DON'T CLICK IF YOU ARE PRONE TO ANXIETY ATTACKS If Shepard tones are paired with things ...

The film presents the alien civilization's advanced understanding of human mental processes and of their resulting behaviors and social interactions. The video offers detailed, accurate and verifiable proofs that these mental processes are deeply flawed and through their sheer existence, will inevitably lead to collective decisions bringing about our ...

The movie is laced throughout with a language of the aliens race. Just like we have many languages on Earth, so do they on their planet. One of those languages is a weapon on their world. Another language makes machines move, another language provides energy, another language allows them to travel from one place to another, etc. This is a large part of their ...

I imagine any premise that proved to the viewer a boolean-logic impossibility, objectively, would cause a lot of people to flip. That is, self-contradicting circular logic, showing that something must be true because it's false and vice versa. Anything that would knock down fundamental axioms of logic. The major advantage would be that people would ...

Insanity. n. mental illness of such a severe nature that a person cannot distinguish fantasy from reality, cannot conduct her/his affairs due to psychosis, or is subject to uncontrollable impulsive behavior. By this criteria, any successful advertisement causes insanity. Ditto any propaganda or indoctrination which "takes".

Photosensitive seizures Primitive lifeforms sometimes end up causing seizures with primitive forms of what the Majestic Zeta Reticulans can accomplish with properly crafted long form videos. The simple versions? cause seizures... flashing lights of the wrong form. Like a baby babbling causing headaches. Long form versions can reprogram the conscious - way ...

For something like this, I think it is best to stay away from too detailed a scientific explanation, or at least anything that refers in too much detail to how it works. We all understand that our psyches are influenced by what we see and hear. You don't need science to imagine that there could be some sights and sounds that are just too much to bear. You ...

You need to look up Festo. They're the company behind those viral youtube videos of flying penguins and birds. Most of their products are normal servos and actuators - electrical, pneumatic and hydraulic. Their experimental stuff are meme worthy (just search for "festo" on youtube) . However, they do sell this pneumatic muscle: https://www.festo....

Does it matter? Sometimes things don't need a full explanation. We never learn why Phil is forced to relive the same day over and over in Groundhog Day. We don't get to hear or read Monty Python's "Funniest Joke in the World". (How could we? It would kill us too!) If the means by which the movie drives the viewer insane is not important to the plot ...

Personal Future The movie changes itself to fit the viewer, and even presents itself differently to multiple people who are viewing it at the same time. The movie would show the viewer themselves acting out the thing the alien wants them to do, and it does so in a way that convinces the viewer that this is their future and that it is inevitable.

There is a group at UC Boulder working on Artificial muscles (https://doi.org/10.1002/adma.202003375) that are made out of small, aligned plastic pouches which contain an electrostatic fluid which expands and contracts upon creating a potential difference across all pouches. By designing pouches in various shapes and by changing the fluid volume, various ...

Conspiracy theory What you describe is partially possible; you can get a small portion of humanity to get aggressive and murderous with the right push. Case in point: Pizzagate. It's just a stupid fabrication about a polictician using a chain of restaurants to sell babies to satanists. This could have ended there, but Youtube and other social media had ...

Meme. A movie that produces doubt and suspicion about the underpinnings of civilization (examples: rule of law, democratic ideals, civil society) with slick, plausible and easy to digest ideas that augment tropes and concepts already circulating in the populace. The old tropes and concepts which the movie augments have themselves persisted because these ...

Hydrogen ion fusion. This accounts for the glow. Radiation! Your engine generates power thru hydrogen fusion. That is not particularly exotic sci fi. https://en.wikipedia.org/wiki/Fusion_power#Deuterium,_tritium Hydrogen ion thruster. Nothing too edgy here either. https://en.wikipedia.org/wiki/Ion_thruster Your fusion engine likes the heavy hydrogen ...

Sentience Off-Switch. In the distant past some apes were artificially given sentience by a race of advanced aliens.* These apes became modern humans. When these aliens performed the uplift they added a failsafe that the sentience could be deactivated by issuing a certain visual pattern. The pattern only works when observed in its entirety at the correct ...

Hypnosis. The aliens have abducted countless humans and experimented extensively on their brains. From this, they were able to create the perfect combination of words, music, visuals, etc. to put a human being into a hypnotic trance state. From there, they are able to subtly implant false memories or suggestions in them that can nudge at least a few of ...

Oxigen (...) what is the highest mass-efficient pathway for production of power in both forms, using any (or any combination) of the following available materials either as reactants or catalysts? Oxigen is used both for burning and generating electricity. In both ways the hydrogen combines with the Oxigen and is able to release an electron because of the ...

Long ago (in the 1950s), Robert A. Heinlein used "single-H" -- stabilized monatomic hydrogen (usually stored as a liquid, presumable at cryogenic temperatures though this was never mentioned) in a number of his novels and stories set in the same universe as The Moon is a Harsh Mistress, The Rolling Stones, etc. He used it mainly because it was the ...

It's not the movie itself, it's rather the movie and what they spray in the room where the movie is projected. Psychedelic drugs are known for having their effect depending on the "set" of the user, meaning their mental state at the moment of the assumption being capable of surfacing latent psychosis. Put the two together, with a movie which ...

Theoretically, it's impossible. But what's this forum for, eh? When you say "insane", I will assume you mean psychosis, a symptom which causes difficulty to discern what is real. There are many different disorders which can manifest psychosis, but for a large part they only manifest in people with specific genetics or that have been involved in ...

It is a trope of science fiction that there are so-called "basilisks" that will neurologically impair anyone who views them. These things are visual patterns/shapes/whatever that human brains (or perhaps any brain) cannot process without being harmed in some way (think about bricking an electronic device). Common examples are the movie Bird Box, an ...

Probably not, but other things can be. The fact that DNA and RNA use a pentose backbone doesn't mean that any DNA analogue needs to have a sugary backbone, and not any random monosaccharide will necessarily work. The important thing about ribose is the structure, meaning the actual literal 3-dimensional shape and connectivity of the molecular fragment that ...

It must be a Pentose or a Hexose From what I've seen the sugar must be a pentose, having 5 carbons, or a hexose, having 6 carbons. It is also of vital importance for there to be a phosphate "pathway". Xylose may be a good alternative sugar, and I like that it has "X" in it like XNA. Xylonucleic acid (formally XyloNA) is also a thing, ...
